The logical setup is echo user defined and entered by the user using a BIOS that allows for a user echo defined fixed disk type. In my case, I patched the BIOS ROM to allow for the echo user type I had chosen. echo echo Be aware that DOS uses 1 less cylinder than specified in the fixed disk echo parameter table. This is because the last cylinder is considered the echo diagnostic cylinder. If you wish to use the diagnostic cylinder for data, echo increase the number of cylinders specified during the setup by 1. Only do echo this if you do not want the diagnostic cylinder available. In my case, echo I entered 545 as the number of cylinders during the setup. This allows echo me to use all 544 cylinders for data. echo echo One additional note, the astute reader will have discovered that the echo physical parameters give 416,176 sectors available on the CP-3204.

So, FDISK will also rem reserve the first track of each logical drive for the partition table. rem Since the partition table only requires 1 sector, DOS is wasting your hard disk rem space.

Sectors are rem numbered starting with 1. rem Note: The upper 2-bits of the cylinder number is contained in the upper rem 2-bits of the byte for the sector number. This means the maximum rem sector number is 63 and the maximum cylinder number is 1023. rem Remember this when you are ready to prepare the partition tables rem for your fixed disk. Study the partition tables shown later in rem this document. rem rem The PARTITION STATUS byte is actually the drive number select byte. rem Since the 1st hard disk is assigned the drive number 80, the partition rem with the status byte equal to 80 will be the boot partition. Only one rem partition can be the active (boot) partition. By changing the PARTITION rem STATUS byte and the partition boot program active partition byte to 81, rem you could boot from the 2nd fixed disk instead of the 1st fixed disk. rem For a DOS partition, the STARTING parameters define the physical location rem of the logical drive boot sector. For an EXTENDed partition, the STARTING rem parameters define the physical location of the beginning of the EXTENDed rem partition. This will correspond to the physical location of the partition rem table for the first logical drive in the EXTENDed partition. rem The SYSTEM byte indicates the type of partition. Valid SYSTEM bytes are rem listed on the page before the partition table definition for drive C: shown rem later in this DOC file. rem The ENDING parameters define the physical location of the end of the rem partition for both a DOS partition and an EXTENDed partition. rem For a DOS partition, RELATIVE SECTORS is the number of physical sectors rem in the partition before the logical drive boot sector. This number will rem correspond to the number of hidden sectors in the BIOS Parameter Table. rem For the fixed disk EXTENDed partition, RELATIVE SECTORS is the number of rem physical sectors in the DOS partition. This corresponds to the number of rem physical sectors before the beginning of the EXTENDed partition. For an rem EXTENDed partition for a logical drive, RELATIVE SECTORS is the number of rem physical sectors in the fixed disk EXTENDed partition that are before the rem partition sector for the logical drive. rem For a DOS partition, NUMBER OF SECTORS is the number of sectors allocated rem to the logical drive. For the fixed disk EXTENDed partition, NUMBER OF rem SECTORS is the number of sectors allocated to the EXTENDed partition. For rem an EXTENDed partition for a logical drive, NUMBER OF SECTORS is the number rem of sectors allocated to the next logical drive. rem The partition table for each logical drive I have setup on my fixed disks rem is shown later in this DOC file. Study and understand the partition tables rem before you try to setup the partition tables for your fixed disk. The rem partition tables are what allow the fixed disk to be divided into logical rem drives. Be careful as you setup the partition tables on your fixed disk. rem A few additional items and caveats. You MUST use DOS version 5 or higher rem in order for the partition structure described in this document to be rem recognized by DOS. Also, FDISK does not recognize the partition structure rem I have setup on my fixed disks. But, since the partition structure is rem known, FDISK is NOT really needed. In fact, the system will hang if I try rem to run FDISK. rem :BOOT rem D O S B O O T S E C T O R rem ═══════════════════════════════════════════════════════════════════════════════ rem The JMP instruction is to end of BIOS Parameter Block.

When the rem entire 2nd fixed disk is setup as an EXTENDed partition, the first sector rem contains the master partition table. This is shown above. Since there rem is an additional logical drive on the disk, an additional partition table rem is required for the first logical drive on the disk. In order to conserve rem disk space and maintain the same logical structure as the 1st fixed disk, rem the additional partition table is placed in the 2nd sector on the disk. rem rem The second sector then contains the partition table for the first logical rem drive AND the BIOS Parameter Block. This is possible because the DOS boot rem program is not required. The starting location entered in the partition rem table for first logical disk is the same as the starting location entered rem in the master partition table. Study the master partition table above and rem the partition table for the first logical drive on the next page. Make rem sure you understand what is happening before you try this with your rem particular system. rem rem F I X E D D I S K D R I V E P A R T I T I O N T A B L E rem ═══════════════════════════════════════════════════════════════════════════════ rem FDISK2 VOL1 ── logical drive G: rem ┌──────┬────┬────────────────────┬────────────────────┬───────────┬───────────┐ rem │ │ │ Starting Location │ Ending Location │ Relative │ Number of │ rem │System│Boot│Side Cylinder Sector│Side Cylinder Sector│ Sectors │ Sectors │ rem ├──────┼────┼────────────────────┼────────────────────┼───────────┼───────────┤ rem │BIGDOS│ No │ 0 0 2 │ 14 135 51 │ 1 │ 104039 │ rem │EXTEND│ No │ 0 136 1 │ 14 271 51 │ 104040 │ 104040 │ rem │unused│ No │ 0 0 0 │ 0 0 0 │ 0 │ 0 │ rem │unused│ No │ 0 0 0 │ 0 0 0 │ 0 │ 0 │ rem └──────┴────┴────────────────────┴────────────────────┴───────────┴───────────┘ rem Listed below is the RELATIVE location of each byte in the partition table. rem The 16-byte list is repeated for each line in the partition table.
